Oh you just touched s nerve there.... My wife was all over me today... Cuz I kept tracking snow in when I came in for bathroom breaks today.... Plowed all day... Freaking got 18 " of snow whole we were gone.I keep threatening to get one of those Roomba floor scrubbers. Can't keep up anyway, between the dog and Ken tracking in (in 50 years I have never, EVER been able to get him to take off his shoes when he comes in the house!) so instead of a heavy scrubbing every couple of days at least I could stay on top of it a little bit by running the Roomba just before bed and do a weekly heaving mopping. I hate the floors not being clean. Kendra crawls on these floors, and if they are gritty that bothers her hands and knees, not to mention that everything that gets on the floor ends up on her hands. I do love my Roomba vaccuum. I can't push the big Dyson as easily any more, so the Roomba gets run almost daily. Then I do a deep vacuuming every couple of weeks, and that's been a good system here. Now with the dog, I suppose I should up the big vacuuming to more often, but I don't want to.
